Definitions
- the invention relates to a profile arrangement, in particular for a refrigerator and / or freezer, comprising at least one base, at least one fastening arrangement, at least one sealing arrangement, with at least one hollow chamber, at least one profile element, and at least one magnetic element, with at least one with which Base via at least one movement arrangement which at least partially protrudes into the sealing arrangement.
- profile arrangements have already been described in the prior art. These profile arrangements have the important function, especially when used in refrigerators and / or freezers, to seal the design-related gap between the closure element and a body, to compensate for tolerances and, if magnetic profile arrangements are used, to ensure that the refrigerator door is closed on the body by means of magnetic adhesive force .
- the tolerance compensation and the stroke of the profile arrangement take place by means of different bellows constructions, which can be clearly seen in the field of view of these profile arrangements.
- EP 0599161 B1 discloses such a generic profile arrangement.
- This profile arrangement is designed as a sealing arrangement for the door of a refrigerator and / or freezer, with a heat-insulating housing, the opening of which can be closed with a door, the side facing the opening, equipped with an inner lining, is arranged around the edge of the door , Bellows-like magnetic seal, which is equipped with a sealing head and a sealing base, which are connected to one another with flexible walls designed as expansion folds, the sealing base being anchored in a receiving groove on the inner lining that tapers on the opening side and is directed towards the door opening, during the with a magnet afford sealing head rests in the closed state of the door on the opening edge of the housing and holds the door on the opening edge, the sealing head for Sealing foot is arranged laterally offset, which is equipped with a bulge on one side which cooperates with an undercut in the receiving groove and which is arranged opposite to the lateral offset closer to the sealing head, the side of the sealing foot opposite the bulging being supported
- a profile arrangement in particular for a refrigerator and / or freezer, comprising at least one base, at least one fastening arrangement, at least one sealing arrangement, with at least one hollow chamber, at least one profile element, and at least one magnetic element, with at least one , at least partially protruding into the sealing arrangement, movement arrangement is characterized in that two movement arrangements that protrude into the sealing arrangement and are positioned approximately opposite one another are arranged, that a first movement arrangement is arranged approximately orthogonally to the base and approximately parallel to the profile element, that a second movement arrangement is arranged approximately parallel to the base, and is connected to the hollow chamber so that the neutral fiber NF of the profile arrangement is arranged approximately the same as and parallel to the bending line BL of the magnetic element.
- the profile arrangement according to the invention but also the magnetic element, it is now possible to introduce the profile arrangements into refrigerators and / or freezers without the need for laborious welding into prismatic frames so that this can be achieved without welded joints.
- the bending line BL or the neutral fiber NF is advantageously the Profile arrangement dimensioned or designed in such a way that when laying in corner areas of refrigerators and / or freezers a radius is possible which is approximately 40 mm and which means that the mechanical stress of the profile arrangement according to the invention is only tensile stress and not Compression, as in the known prior art.
- the neutral fiber NF also known as the zero line.
- the stress does not cause any tensile or compressive stress. It runs in straight bars made of isotropic materials through the geometric center of gravity of the cross-sectional area. In the fiber furthest away from the neutral fiber in the vertical direction, the tension is at its maximum.
- the dimensioning of the magnetic element must also be optimized accordingly, in particular here the axial moment of resistance, in order to achieve the necessary surface adhesive force of the magnetic element.
- Another advantage of the profile arrangement according to the invention is that the neutral fiber NF of the profile arrangement is spaced apart and is arranged parallel to the bending line BL of the magnet element. As a result, an optimal laying of the profile arrangement according to the invention can be achieved with the most varied of geometries (width, length) of refrigerators and / or freezers.
- the neutral fiber NF of the profile arrangement is spaced a maximum of 5 mm apart and is arranged parallel to the bending line BL of the magnetic element. Thanks to these structural or geometric possibilities, it was surprisingly found that the profile arrangement, when used as intended, on a closure element or a refrigerator and / or freezer, in particular in the corner areas, can be introduced in a very narrow radius without the need for optical or mechanical Impairments are recognizable.
- the magnetic element has an axial geometrical moment of inertia l z of about 20-100 mm 4 , preferably about 35-65 mm 4 .
- profile arrangement Another advantage of the profile arrangement is that the hollow chamber of the sealing arrangement is arranged approximately directly opposite the base of the profile arrangement.
- This structural design of the profile arrangement also makes it possible to produce it economically and inexpensively, and to make it so flexible that, on the one hand, simple and easy-to-assemble insertion into closure elements or refrigerators and / or freezers is possible, and on the other hand, very tight ones Laying radii can be implemented in particular in the corner areas of the closure elements and of the refrigerators and / or freezers.
- the profile arrangement is advantageously designed such that the at least one movement arrangement has at least two movement sections which are arranged approximately opposite one another and connected to one another via at least one connecting element.
- simple assembly in closure elements and refrigerators and / or freezers can be implemented without the actual sealing or closure function of the profile arrangement being impaired.
- the first movement arrangement has at least two movement sections which are arranged approximately opposite one another, approximately parallel to the profile element and connected to one another via at least one connecting element.
- very narrow installation radii of about 45 millimeters can be achieved when mounting in closure elements as well as refrigerators and / or freezers, especially in the critical corner areas, without optical distortions or mechanical impairments being discernible on the profile arrangement.
- the second movement arrangement has at least two movement sections, which are arranged approximately opposite one another, at approximately an acute angle to the base element, via at least one connecting element, connected to one another.
- very narrow installation radii can also be achieved in the critical corner area of the closure elements and refrigerator and / or freezer without the installed profile arrangement having any visual impairments.
- the sealing arrangement and / or the movement arrangement and / or the profile element is made of a flexible, polymeric material, with a Shore A hardness according to DIN EN ISO 868 of about 50 - 100, preferably 60 - 90, particularly preferably 70-80. This enables the profile arrangement to be manufactured economically and inexpensively without any problems.
- the sealing arrangement also has at least partially a polymeric material, selected from the group of thermoplastic elastomers, for example olefin-based and / or urethane-based, crosslinked thermoplastic elastomers based on olefin, thermoplastic copolyester, the Styrene block copolymers (SBS, SEBS, SEPS, SEEPS and MBS) and thermoplastic copolyamides.
- the Weihraum-containing materials preferably polypropylene, acrylonitrile-butadiene-styrene copolymer, polycarbonate, polyvinyl chloride, polymethyl methacrylate, polyethylene terephthalate,
